Applloation filed April 9, 1929. Serial No, 353,787,

This invention relates to a device designed for use in supplyingelectric energy from the usual lighting circuit of a building, to thevstarting motor of a motor vehicle, thereby eliminating the possibilityof exhausting the electric energy of the battery of the vehicle duringcold weather.

An important object of the invention is to provide a switch in the formof a plug to be inserted in a socket in circuit with the battery andstarting motor, the plu being of a construction to automatically reakthe circuit between the battery and starting motor,and complete acircuit between the motor and lighting circuit of the building or garagein which the vehicle is housed.

Another object of the invention is to provide a socket member havingcontacts therein which contacts complete a circuit between the 2 batteryand motor when the plug is removed, so that the starting switch may beactuated in the usual and well known manner for starting the vehicle.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spiritof theinvention.

Referring to the drawings:

Figure 1 is a view illustrating the use of the device forming thesubject matter of this invention.

Figure. 2 is a longitudinal sectional view through the socket member ofthe device.

Figure 3 is a longitudinal sectional view through the socket member andplug.

Figure 4 is a sectional view taken on'line 4-4 of Figure 3.

Figure 5 is a diagrammatic view showing the circuits.

Referring to the drawings in detail, the device embodies a switchincluding a socket member 5 which is secured to the motor vehi cle atany convenient location, and as shown the reference character 15.

the socketmember includes spring contact arms 6 that have curved ends 7normally contacting to complete a circuit therethrough.

One of the arms 6 is in circuit with the battery of the motor vehicle,through the wires 8 and 9 whilethe opposite arm is in circuit as withthe starting switch. 10, through the wire 11.

The wire 12 completes the circuit between the motor A and contact member130i the starting switch, while the wire 14 is the w ground wire leadingfrom the. motor. Thus it will be seen that under normal conditions thestarting motor A may be thrown into operation to start the motor of thevehicle, by operating the starting switch 10. The ground wire for thebattery, isindicated by The socket member 5 also includes a contact arm-16 to which the ground wire 17 is connected. Cooperating with the socket717 member is a switch plug 18 which is of a diameter to closely fitwithin the opening of the socket member, the forward end of the plugbeing tapered to fit within the'tapered opening 19 in the forward end ofthe socket member. This plug is constructed of insulating material andissectional in formation, the sections of the plug being held togetherby means of the bolts 20 that pass through aligning openings in thesections. w

Adjacent to the forward end of the plug, is a contact plate 21 to whichthe wire 22 is I connected, which wire leads to the transformer 23 whichis in iiircuit with the wires 24 and 25 that constitute the lightingcircuit of the garage or building in which the vehicle supplied with thedevice forming the subject matter of this invention is housed, therebyproviding a switch 26 for controlling the circuit.

Another contact plate is secured to the plug, and is indicated by thereference character 27, which plate is in circuit with the wire 28constituting the positive .wire of the circuit. W

The wires forming the circuit between the plug and transformer are'woundon the reel 29 which is mounted on the plate 30, that in turn is securedto the wall of the garage or building so that the-wires may be readilythe device, it is only necessary to lift the hood and place the plug inthe socket member whereu on the circuit between the motor vehicle atteryand starting motor is broken by the contact of one of the switch arms 6with the insulated side of the plug. Electric energy now will assthrough the transformer from the lighting circuit of the building, fromwhere the circuit will pass to the arm 16 through the plate 27 to theground wire 17. Electric energy will also pass through the wire 22,plate 21, and contact arms 6 through the starting switch 10 and 'wire 12to the motor A causing the motor to operate to start the internalcombustion engine or motor of the vehicle, thereby relieving the usualbattery of the vehicle of undue strain.
